DEVICE FOR PREVENTING FRAUDULENT REFILLENG OF BOTTLES.

SPECIFICATION forming part of Letters Patent No. 604,545, dated May 24,1898.

Application filed June 28, 1897- T0 all whom it may concern:

Be it known that I, MEYER ROSENBERG, a citizen of the UnitedStates,residin gin Brooklyn, Kings county, State of New York, haveinvented a certain new and useful Device for Preventing FraudulentRefilling of Bottles, of which the following is a specification.

This invention relates to that class of inventions which has for itsobject the preventing of fraudulent refilling of bottles; and itconsists, essentially, of a novel stopper provided with a cup-valveatits lower end and a Wheel having vanes or cups at its periphery,revolubly mounted above the valve. These and other novel features of theinvention will be more fully explained in the below specification andthe accompanying drawings, in which Figure 1 is a sectional view of theimprovement. Fig. 2 is a cross'section taken in line X X, Fig. 1. Fig. 3is an elevated view of the turbine wheel. Fig. 4 is an enlargedsectional view of the valve-cup.

Similarletters referto similar parts throughout the several views. I

A represents the neck portion of a bottle. This portion is provided withtwo indentations A, situated adjacent to the upper end of the neck andare adapted to receive two spring plugs or pistons, hereinafter referredto.

B represents a stopper permanently secured in the neck of the bottle bymeans of the above-mentioned spring-plugs O, which are slidably mountedunder spring tension in two pockets or cavities B, situated in the upperexterior portion of the stopper. The face of the forward end portion ofeach piston is made slanting in order that the piston may spring backand permit the stopper to be introduced in the neck of the bottle bysimply eXertinga pressure on the top of the stopper. The up per end ofthe stopper is provided with a lip 3 adapted to limit the amount ofinsertion of the stopper in the neck of the bottle. The central innerportion of the stopper is provided with a bushing or casing D, open atboth ends, the lower end portion of the casing terminating in a circularvalve-seat D".

E represents a valve-cup comprising a metal thimble E, and a leathercovering E the upper portion of which forms an annular flange E adaptedto normally be in contact with Serial No. 64:2,622. (N0 model.)

the lower circular portion of the bushing. The valve-cup is looselyconnected with the bushing by means of a link connection E which permitsthe Valve to open by gravity when the bottle is tipped over fordischargin its contents. In the large central portion of the bushing isrevolubly mounted a wheel F, provided with cups or vanes F on itsperiphery. This wheel is actuated by the flow of liquid admitted throughthe cup-valve and striking the vanes and is adapted to admit air to thebottle when emptying the same with out interfering with theoutwardlygoing stream of liquid, thus promoting an even flow and rapiddischarge of the contents of the bottle. i The turbine wheel furtherserves the purpose of preventing the valve-cup being reached andtampered with by any tool i11- serted through the upper opening of thestopper, as the wheel completely covers the space intervening the upperopening of the stopper and the valve-cu p. The bushing forming thecasing for the wheel bein g preferably made of metal will always retainits shape no matter how tight the stopper may fit in the neck, thusinsuring a smooth and unobstructed space for the wheel in which torevolve and will also afford a uniform seat for the cup forming thevalve.

In the manufacture of this device I prefer to mold the stopper proper ofrubber or some other flexible material in order to enable me to forcethe bushing in place through the lower opening of the stopper and thussimplify the manufacture of the device.

The stopper is secured in the neck of the bottle by simply forcing thestopper down in the same until the spring-plugs are situated oppositethe indentations in the neck. The plugs will then snap out and engagethe indentations, thus locking the stopper permanently against anydisplacement.

The operation of the device is as follows: The bottle being held withthe neck pointing downward the valve-cup will assume the positionindicated by the dotted lines in Fig. 1 and permit the liquid to flowout and successively fill the cups on the wheel and cause the same torevolve and successively discharge the contents of the cups at the upperend of the stopper, from whence it flows through the upper opening ofthe stopper. In attempting to refill the bottle the valve-cup will befilled and forced back toits normal place, the spherical end portion ofthe cup engaging the valve-seat, and when the liquid overflows the cupthe annular leather flange surrounding the upper portion of the cup willspread out and form a second tight joint for preventing the liquidreaching the interior of the bottle.

I do not desire to limit myself to the particular construction hereinshown and described, as I am aware that many changes may be made in thesame without departing from the spirit and scope of my invention. Forinstance, the stopper may be made of hard material, thus making itunnecessary to use a bushing or casing for the wheel. The means forsecuring the stopper in the neck of the bottle may also differ from theone shown, and the stopper may be used with or Without a lip at itsupper end.

Having thus described my invention, what I claim as new, and desire tosecure by Letters Patent, is-

1. In a bottle, the combination with a neck having indentations on itsinner surface adjacent to the upper end of the neck, a stopper providedwith spring-plugs adapted to engage the said indentations, said stopperbeing hollow and provided at its inner central portion with a bushing orcasing, the lower end of which terminates in a circular valveseat, ahinged valve-cup comprising a metal thimble, normally engaging saidvalve-seat, said valve-cup being provided at its upper edge with anannular flexible collar adapted to engage the upper portion of thevalve-seat, abucket-wheel revolubly mounted in the central portion ofthe bushing, substantially as described and for the purpose set forth.

2. In a bottle the combination of a flexible hollow stopper permanentlysecured to the neck of the bottle, and provided at its upper end with anannular flange overlapping the upper circular edge of the neck of thebottle, a bushing mounted in the interior hollow por tion of thestopper, the lower portion of said bushing terminating in a circularvalve-seat, a hinged valve-cup normally engaging said valve-seat, saidValve-cup being provided at its upper edge with an annular flexiblecollar adapted to engage the upper portion of the valveseat, abucketwheel revolubly mounted in the central portion of the bushing,substantially as described and for the purpose set forth.

3. In a bottle the combination with a neck having indentations on itsinner surface adjacent to the upper end of the neck, a hollow stopperprovidedwith spring-plugs adapted to engage the said indentations, thelower portion of said stopper being provided with a circular valve-seata hinged valve-cup comprising a metal thimble normally engaging saidvalve-seat, said valve-cup being provided at its upper edge with anannular flexible collar adapted to engage the upper portion of thevalve-seat, a bucket-wheel revolubly mountedin the central portion ofthe stopper, substantially as described.
